The products feature three lightweight, waterproof solar panels that generate up to four watts of power – enough energy to charge nearly any handheld electronic device.

According to Depot: "By carrying a solar charging bag, business professionals, students and travellers now have the ability to charge their mobile devices with renewable power on-the-go and unplug from the electricity grid."

The bags and backpacks can be used with a variety of electronic devices, including Blackberry devices, MP3 players, digital cameras, PDAs and nearly all brands of mobile phones.
